Hi Everyone    :)
Hi Everyone    :)
          
          
Like most of the folks here I am delighted with my L1 classic. I am especially happy with it since I found the solution to a problem I have been having for quite some time.

When I first got my L1 ( months ago ) and plugged in my acoustic guitar I was amazed at the sound quality I experienced, it was perfect in my opinion. I had never heard my acoustic guitar sound that good.

Then I put a vocal mic in front of the system .... and, well, this is when things changed. Although the sound was still pretty good I could tell that the guitar EQ had changed and become thinner, not as rich and full. I also found myself spending a lot of time working on getting a vocal sound I was happy with.

Using these techniques helped improve things incrementally but were not a 100% fix, even when I tried them all at once.

After alot of experimentation I finally hit on a complete fix that works well for me. I thought I would post it here in case it might benefit someone else, especially those of you that are using a harmonizer and ocassionally getting wobbly harmonies that are not a result of your voice ( guitar bleed thru will do that to a harmonizer ).

So here is what I did :
So here is what I did :


#  I am using a TC Helicon Voicelive ( for harmonies ) as an insert on the vocal channel. So, I used it to add compression to the vocal channel. This boosted the vocal volume considerably and allowed me to turn the vocal channel down from 2 o'clock to 10 o'clock ( on the remote ). This had the effect of reducing the sensitivity of the vocal channel while still retaining a strong and powerful vocal volume and performance.

#  I also purchased a Crown CM 311A headset mic which is known for it's great isolation and feedback rejection properties. ( As an aside I have to say that this is an excellent mic, especially when combined with Cliff's wonderful preset. It is the best sounding mic I have tried to date thru the L1, in my humble opinion )

#  I also left the gate ( via the Voicelive ) turned on, the threshold on the gate is set at -31db.
